Hku martians prototype: common questions

What microcontroller does the Hku martians prototype use?

The Hku martians prototype is built around the Raspberry Pi 5, from the Raspberry Pi family.

How big is the Hku martians prototype PCB?

The Hku martians prototype measures 99.6 × 99.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Hku martians prototype?

51 components, from 23 distinct parts. The full bill of materials is listed on this page.

Where can I download the Hku martians prototype design files?

From the iloevera/hku-martians-prototype repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Hku martians prototype design in my own project?

Yes, under the terms of its CERN-OHL-W-2.0 license, which iloevera chose for the repository.

Can I test firmware for the Hku martians prototype without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Raspberry Pi firmware against it before you order a PCB.
